Answer:
Step-by-step explanation:
Our equations are

Let us understand the term Discriminant of a quadratic equation and its properties
Discriminant is denoted by D and its formula is

Where
a= the coefficient of the 
b= the coefficient of 
c = constant term
Properties of D: If D
i) D=0 , One real root
ii) D>0 , Two real roots
iii) D<0 , no real root
Hence in the given quadratic equations , we will find the values of D Discriminant and evaluate our answer accordingly .
Let us start with

Hence we have two real roots for this equation.


Hence we do not have any real root for this quadratic

Hence D>0 and thus we have two real roots for this equation.

Hence we have one real root to this quadratic equation.
Answer:
Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank.
12/4=3
So if I added another 1/4 to the capacity:
It could hold 15 gallons.
All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.
15x2=30
30 bottles.
Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.
Step-by-step explanation:
The y-intercept of this line is the value of y at the point where the line crosses the y axis.
I think is should be (5,0)
Answer:
The team made x<u><</u>53 points total.
Step-by-step explanation:
1/4+1/10 is 7/20 or 0.35 in decimal form. If they both together scored 21 points then you can add another 7/20 (21 points) and have 14/20 (42 points). You have 6/20 more left. If you can solve what 1/20 could be then you would find the answer. Does this helps?
